NETRI, an industrial start-up, develops in vitro neuro-organs-on-chip models based on human stem or primary cells, for the dermo-cosmetics, pharmaceutical and nutritional health industries. NETRI's technological innovations mimic human anatomy through cellular compartmentalization. The versatility of its devices enables different cell types to be (co)cultured, from the innervation of monolayer keratinocytes to the vascularization of reconstructed skin. Its devices are compatible with standard analyses (imaging, ELISA assays, etc.) and innovative analyses (recording of neuronal electrical activity). NETRI commercializes high-throughput and easy-to-use organs-on-chip devices, as well as R&D services.
